Webloading is affected by vehicle speed, tire pressure, ground unevenness and depth of cover. The pressure from the live load results in both hoop stress and longitudinal stress in the buried pipe. The CEPA equation [10,11] can be used to determine the hoop stress from the live load as 𝜎H_live= 3 b𝑝live( 𝑡) 2 1+3 z 𝑝i ( 𝑡)
